MCIMX233CAG4B 概要
An ARM9 microprocessor is a 32-bit RISC core that executes the ARMv5TEJ instruction set, including Jazelle Java acceleration and DSP extensions, sitting in the broader MPU hierarchy below Cortex-A application processors but above microcontrollers in compute capacity. This places the i.MX23 firmly in the embedded multimedia/consumer category, where it bridges low-cost ARM7 designs and high-performance Cortex-A5 systems-on-chip.
Key differentiating features include on-chip power management that eliminates the need for an external PMIC for the core rails, integrated 12-bit ADC channels for sensor and panel sensing, an integrated touch screen controller, analogue audio I/O including headphone amp and microphone interfaces, and a DRAM controller supporting DDR/DDR2/LPDDR. Together these blocks allow the i.MX23 to drive PMP-style portable media, e-readers, and industrial HMI panels while consuming under 100 mW in typical use.
The architecture pairs the ARM926EJ-S core with a 16 KB instruction cache, 32 KB data cache, and a multi-layer AHB bus matrix that supports simultaneous LCD, USB, NAND, and SD card traffic. Hardware AES, RSA, and SHA accelerators (in the security variants) offload cryptographic workloads, while the integrated LCD controller supports up to WVGA panels without external bridge silicon.
Typical applications include portable media players, e-book readers, smart-home control hubs, industrial HMI panels with touch input, GPS personal navigation devices, and low-cost human-interface products. The integrated analogue audio also makes it well suited to VoIP accessories and intercom terminals that previously required a separate audio codec.
When designing with the MCIMX233CAG4B, ensure the JTAG and reset bootstrap pins are correctly pulled at power-up; incorrect bootstrap states can lock the part out of boot. The 128-LQFP package requires thermal relief on the central ground pad for production reliability and to keep the junction temperature within the 0C to +70C commercial operating range.

主な用途
MCIMX233CAG4B の用途: 6 件s: Portable Media Player (PMP), E-Reader / E-Book Terminal, Industrial HMI / Touch Panel, GPS Personal Navigation Device (PND), Smart Home Control Hub, VoIP Intercom / Audio Accessory.
Portable Media Player (PMP)
The MCIMX233CAG4B fits portable media players because it integrates an LCD controller (up to WVGA), analogue audio output with on-chip headphone amplifier, SD card interface, and USB OTG in one 128-LQFP package. At 454 MHz the ARM926EJ-S core decodes MP3, AAC, MPEG-4, and H.264 baseline video while leaving cycles for UI rendering. The integrated power management cuts idle power to under 10 mW, allowing 20+ hours of audio playback on a single 1500 mAh cell without an external PMIC.
おすすめ
E-Reader / E-Book Terminal
The i.MX23's integrated LCD controller and low dynamic power make the MCIMX233CAG4B a strong fit for e-readers and e-book terminals. The ARM926EJ-S runs e-paper refresh waveforms and Linux-based reader software stacks at 454 MHz, while the integrated power management enables weeks of standby on battery. The 12-bit ADC and touch screen controller support stylus input without extra silicon, cutting BOM for low-cost education and consumer e-reader SKUs in the same 128-LQFP footprint.
おすすめ
Industrial HMI / Touch Panel
MCIMX233CAG4B drives industrial HMI panels because it pairs the on-chip 4-wire resistive touch screen controller with the integrated 12-bit ADC and LCD controller in the same 128-LQFP. The ARM926EJ-S at 454 MHz runs LVGL, Qt, or web-based HMIs smoothly on small panels. Industrial designers select the MCIMX233DAG4C variant for extended temperature, but the MCIMX233CAG4B remains suitable for indoor kiosks and machine HMIs where commercial 0C-70C range is acceptable.
おすすめ
GPS Personal Navigation Device (PND)
GPS PNDs benefit from the MCIMX233CAG4B's integrated audio codec, LCD controller, USB OTG, and SD card slot in a single 128-LQFP MPU. The 454 MHz ARM926EJ-S runs navigation software stacks while the integrated headphone amp drives voice prompts without a separate audio DAC. Low power idle modes let the PND sleep with fast GPS reacquisition, which is critical for turn-by-turn products that wake frequently between route guidance events.
おすすめ
Smart Home Control Hub
The MCIMX233CAG4B is well matched to low-cost smart-home hubs and remotes that need a touch screen, Wi-Fi/802.15.4 co-processor interface, and Linux application stack in a single chip. The integrated power management keeps idle power low so battery-powered remote controls last months on a coin cell, while the 454 MHz ARM926EJ-S runs Z-Wave/Zigbee gateway software and small touch-screen HMI simultaneously. The 128-LQFP footprint is friendly to small-form-factor remotes and wall controllers.
おすすめ
VoIP Intercom / Audio Accessory
VoIP intercoms and audio accessories benefit from the MCIMX233CAG4B's integrated analogue audio I/O, microphone preamp, headphone amplifier, and Ethernet MAC in the same 128-LQFP MPU. The 454 MHz ARM926EJ-S runs SIP stacks and voice codecs while keeping latency low. Compared to designs that bolt on an external audio codec and Ethernet PHY, the i.MX23 collapses the BOM and reduces PCB area for compact intercom panels and audio peripherals.

設計ノート
The i.MX23 integrates the core and I/O power rails, but a 24 MHz crystal and proper decoupling network are mandatory. Place 1x 10 uF bulk + 4x 100 nF ceramic capacitors within 5 mm of the supply pins, following the i.MX23 Hardware Reference Layout. The internal PMU manages the core ramp profile; do NOT add external RC delay circuits on the power rails or the PMIC hand-shake will fail and the part will not boot.
The MCIMX233CAG4B bootstrap pins (BOOT[3:0]) select the boot source (NOR, NAND, SD, USB). Strap them at power-on via 10 kohm pull-ups/pull-downs and verify the levels with an oscilloscope during prototype bring-up. A common failure mode is leaving these pins floating, which forces the part into USB recovery mode and prevents application code from launching from external memory.
Keep the 24 MHz crystal traces short and symmetric, with a continuous ground reference plane beneath. The DDR/DDR2 memory controller is sensitive to trace length matching; for DDR2-400 use +-25 ps skew on the byte lanes and route address/command/clock in a separate layer with reference to ground. Failing to follow the i.MX23 reference layout causes intermittent SDRAM training failures that are hard to diagnose.
